Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the size of electronic apparatus is reduced, then miniaturization is achieved, but electromagnetic mutual coupling increases causing signal interference
Solution Approach 1:
The grounding plate is segmented by forming slots that divide it into separate regions. These slots create electromagnetic isolation between adjacent signal generation devices, preventing mutual coupling while maintaining the compact overall structure of the electronic apparatus.
Solution Approach 2:
Blocking devices are introduced as intermediary elements that are inserted into the slots of the grounding plate. These blocking devices act as electromagnetic barriers that actively prevent signal leakage and mutual coupling between adjacent devices, serving as mediators that isolate electromagnetic fields without requiring physical separation of the devices.
2Quantity of substance
If signal generation devices are placed closer together, then device density increases, but signal interference from mutual coupling worsens
Solution Approach 1:
The grounding plate is divided into isolated regions through slots, allowing multiple signal generation devices to be placed in close proximity while maintaining electromagnetic separation. Each device operates in its own segmented region, enabling high device density without signal interference.
Solution Approach 2:
Blocking devices inserted into the slots serve as intermediary electromagnetic barriers between closely spaced signal generation devices. These intermediaries prevent signal leakage across device boundaries, allowing increased device density while maintaining signal integrity.
3Reliability
If grounding plate is used without slots, then grounding effectiveness is maintained, but electromagnetic isolation between devices is insufficient
Solution Approach 1:
The grounding plate maintains its overall grounding function while being segmented by slots into isolated regions. The slots create electromagnetic barriers that prevent mutual coupling, while the remaining grounding structure continues to provide effective grounding for each signal generation device within its designated region.
Applied Scientific Principles

Function Achieved in This Case
This solution effectively restricts electromagnetic mutual coupling, enhancing signal isolation and enabling the miniaturization of electronic apparatuses by preventing signal interference and maintaining performance for multimedia services.
Implementation Method 1
a closed resonant circuit is independently formed in a signal generation device along the blocking device and the surrounding area of a slot in a ground plate
Implementation Method 2
a blocking device interposed in the slot, which closes the slot, provides an output path of the signal, and blocks an inflow of the signal to the signal generation device
